U's keeper set to face Orient.Sam Walker is in the U's squad to face Leyton Orient on Saturday.
Following Saturday's game, boss Tony Humes will only have two games and two weeks to prepare his side for the first League One game so starting places against Blackpool are up for grabs.
A productive match schedule has yielded four wins out of four but more importantly, individual and team performances have been positive.
Also back in the squad is full back Richard Brindley, who has missed the last two build up games against Bishop's Stortford and West Ham.
Walker is in the U's squad to face the newly relegated Londoners, and will be hoping for some catch up minutes on the pitch ahead of the league season.
Goalkeeping duties have been shared by Chris Lewington and Elliot Parish so far, with the latter impressing enough to be offered a one year contract.
It will be Walker's first appearance of pre-season, having missed the first four friendlies through a knee injury.
